A brief summary: it is not a scary movie per se, each plot twist (and there are not many of them) would be foreseen by a 5 year-old under caught syrup influence, actors can't play... If you want to watch an unintentionally made parody comedy, like any Final Destination, but much worse, then watch this.
Longer story (still no spoilers): The plot itself is very standard for an average horror for teens, yet they forgot to put any logic into characters' actions, making them not just helpless and flawed (which is somewhat expected from a horror movie), but more like mentally disabled or straight dumb. Most deaths in this horrific movie are results of totally illogical and unmotivated actions of characters, which causes strong desire to break something (that is how dumb the plot and dialogues are).
The crew (starred actors) performance is unnatural and provides no entertainment at all... unless you are watching this as a freak show of emotionally handicapped, which wouldn't be advised and is not nice for many reasons. The whole plot can be compressed into 3 sentences (or 10, if add unnecessary details, which are not affecting the plot).
And the screamers... neither of the screaming moments was delivered. None. I would be more terrified with a spam phone call during the lunch break, then with all this movie put together.
In total: I dare to bet, that this review is more entertaining, then this movie.
